Abstract: An apparatus comprising a cavity having interior surfaces or reflecting elements, one or more transmitters configured to receive an electrical signal, transform the electrical signal into an electromagnetic wave signal, and introduce the electromagnetic wave signal into an inside of the cavity, and one or more receivers configured to retrieve the electromagnetic wave signal, transform the electromagnetic wave signal to a corresponding electrical signal, and transmit the corresponding electrical signal to the outside of the cavity is disclosed. The electromagnetic wave signal is contained within the inside of the cavity until retrieved by undergoing a series of reflections or traversals between the interior surfaces of the cavity or the reflecting elements within the cavity. The apparatus may further comprise one or more regenerators configured to re-amplify, re-shape, and/or re-time the electromagnetic wave signal traveling within the inside of the cavity.

Abstract: A wavelength converter for LiDAR systems, such as automotive LiDAR, is disclosed. Implementation of the wavelength converter in LiDAR systems makes possible generation and modulation of laser light in the silicon response region, conversion of the laser light to an eye-safe wavelength for emission and reflection from a target, and efficient conversion of the wavelength of the laser light to the silicon response region. The wavelength converter may implement a single-loop counter-propagating wavelength conversion scheme which provides both up-conversion and down-conversion of the signal within the same loop. The wavelength conversion design also has the potential for vehicle-to-vehicle (V2V) communication to enable a combined LiDAR and V2V communication system.

Abstract: An apparatus and method for wavelength conversion of a signal, for example, a dual-polarization signal, is disclosed. The apparatus implements a single-loop counter-propagating wavelength conversion scheme which provides both up-conversion and down-conversion of the signal within the same loop. Nonlinear wavelength conversion devices in the loop provide both up-conversion and down-conversion of the polarization components of the signal within the loop depending on whether the polarization component travels through the nonlinear conversion device in a clockwise or a counter-clockwise direction. The wavelength-converted signal is available to be extracted from the wavelength-conversion loop. An all-optical wavelength-division multiplexing transponder based on the wavelength-conversion scheme is also disclosed.

Abstract: A data storage system is disclosed that includes a recirculating loop storing data in motion. The data may be carried by a signal via the loop including one or more satellites or other vessels that return, for example by reflection or regeneration, the signals through the loop. The loop may also include a waveguide, for example an optical fiber, or an optical cavity. Signal multiplexing may be used to increase the contained data. The signal may be amplified at each roundtrip and sometimes a portion of the signal may be regenerated.
